conducting heating. If the user requires constant indoor temperature, please reduce
the operating fan speed in project parameter setting when conducting defrosting, to
enhance usage comfort. Users can set the fan status during defrosting through the
wired controller to the lowest fan, current fan or stop the fan:
1) If set wiring controller operate fan speed, the unit air outlet temperature will
be lower, it will influence the comfort.

will enhance usage comfort.
3) If set stop the unit, the unit will stop to operate.
(3) Positive and negative setting
If the user has special requirement on indoor supply air, conduct pertinent setting
in project parameter for different supply air mode.
Positive and
negative
setting
Under this mode, the fan speed setting of fresh air and
discharge is consistent with wired controller
Positive pressure
Under this mode, the fan speed setting of wired controller
is fresh air, the fan speed of fresh air is higher than that of
discharge
Negative pressure
Under this mode, the fan speed setting of wired controller
is discharge, the fan speed of discharge is higher than
NOTE!
